Classifying and Grouping Electronic Images

ABSTRACT

An approach is provided in which a system analyzes a first subject in a first image taken at a first point in time against a second subject in a second image taken at a second point in time. The first image and the second image are captured at a venue. The system determines, based on a time duration between the first point in time and the second point, a probability that the first subject is at the venue at the second point in time. Next, the system computes, based on the probability, a relevance score that quantifies a relationship between the first subject in the first image and the second subject in the second image. Finally, the system assigns the second image to a first image file corresponding to the first image based on the relevance score reaching a relevance score threshold.

BACKGROUND

The embodiments described herein relate generally to image processing. More specifically, the embodiments described herein relate to classifying and grouping images based on detecting image characteristics.

Many people enjoy attending amusement parks, such as theme parks, water parks, etc. Patrons of these parks typically like to memorialize their experience by taking pictures of the sights and activities. One option for a patron is to take their own personal pictures around the park. However, taking personal pictures requires that the patron carry around a potentially expensive device that could get damaged or stolen. Furthermore, taking pictures with a personal device limits the types of pictures that can be captured. For example, taking pictures while on many types of rides is typically infeasible, if not expressly forbidden.

To address the desire for patrons to have photographs taken of their experiences while on a ride, many parks have installed camera systems designed to take pictures at one or more strategic points along the trajectories of various rides. For example, a camera may be situated around the bottom of a roller coaster hump to take a reaction shot of a patron screaming and shouting as she is plummeting toward the ground. These cameras are generally located a select rides, and the cameras that are present tend to be configured to only capture still images. The captured images are usually available for purchase at a gift shop or a kiosk located outside of the ride, and may either be printed on-site or sent to the patron via mail or e-mail. The images for sale tend to be rather expensive to purchase. At the same time, even if a patron is interested in purchasing a photograph as a souvenir, there are typically long lines or waits at the gift shop or kiosk. Accordingly, these negative externalities reduce the likelihood that a patron will be willing to purchase the photograph, which corresponds to a loss of revenue.

DETAILED DESCRIPTION

It will be readily understood that the components of the embodiments described herein, as generally described and illustrated in the Figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the method, computer program product, and system, as presented in the Figures, is not intended to be limited, as claimed, but is merely representative of selected embodiments.

Reference throughout this specification to “a select embodiment,” “one embodiment,” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “a select embodiment,” “in one embodiment,” or “in an embodiment” in various places throughout this specification are not necessarily referring to the same embodiment.

The illustrated embodiments described herein will be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout. The following description is intended only by way of example, and simply illustrates certain selected embodiments of devices, systems, and processes that are consistent with the claims herein.

The embodiments described herein below will make reference to amusement parks. An amusement park is a non-limiting example of a venue that may implement the embodiments described herein. It is to be understood that the embodiments described herein are not limited to the context of amusement parks, theme parks, water parks, etc., and it is to be appreciated that the embodiments described herein may be applied to any venue or location.

FIG. 1 depicts a flow chart (100) illustrating a method for obtaining primary and secondary images. A primary image is captured (102), and an associated primary image file is generated (104). In one embodiment, the primary image is captured by a primary camera device that is placed, for example, at the entrance of the venue or location. The generated primary image file is then stored (106). The primary image file may be compressed using a compression format suitable for images, such as JPEG.

The primary image file may be stored on one or more computer readable storage devices, including but not limited to persistent storage and/or volatile storage. The stored primary image is assigned a unique identifier, IDP (108). IDP may be metadata associated with the primary image file. In one embodiment, IDP corresponds to a numerical ordering of the primary image. For example, IDP of the first primary image captured for the day may be assigned to “1,” “0000001,” etc., the next primary image captured for the day may be assigned to “2,” “0000002,” etc., and the fortieth primary image captured for the day may be assigned to “40,” “0000040,” etc. It is understood that the subject of the primary image is a patron or visitor in a specific venue. Accordingly, a captured primary image is assigned a unique identifier to facilitate finding the image at a later point in time.

It is understood that one or more secondary images are intended to be associated with at least one primary image, and in one embodiment, stored in a common location. As such, for each primary image, a primary image folder in an image database is created and initialized, and the primary image is stored in the image folder (110). In one embodiment, the image folder may also be referred to as a primary image group. Accordingly, a primary image of an individual is captured and stored prior to, or upon entrance, into a venue or location, and the primary image represents a foundational image of a respective primary image group.

As shown in FIG. 1, a primary image is captured by a primary camera device at a select location in a venue. One or more secondary camera devices may be placed at a variety of other locations throughout the venue, such as at points of interest or other high traffic areas. For example, in the context of an amusement park, the secondary cameras may be positioned outside of rides or attractions, on the rides or attractions themselves, at concession stands, at gift shops, or at any other point of interest. In one embodiment, each secondary image is captured by a respective secondary camera device. That is, each person at the venue or location may be associated with a plurality of secondary images. In order to prevent the flooding of data, the secondary camera devices may be configured to capture secondary images at select time intervals. For example, a first secondary camera may be configured to capture secondary images at a first set of intervals, and a second secondary camera may be configured to capture secondary images at a second set of intervals, with the first and second sets of intervals being different. Accordingly, one or more secondary images may be taken at various points of interest throughout a venue.

In one aspect, each received secondary image is classified and linked to a respective primary image. With reference to FIG. 2, a flow chart (200) is provided illustrating an exemplary process for classifying a secondary image. A captured secondary image file is received (202), which includes generating a secondary image file from the captured secondary image, and storing the secondary image file in a storage device. In one embodiment, the secondary image is captured by a secondary camera device. The secondary camera device is configured to capture still photographs featuring one or more people. In one embodiment, the secondary camera device is further configured to record video featuring one or more people. The video recording may be assigned to a secondary image that is captured along with the video recording, such that the video recording and secondary image are stored together. In one embodiment, the secondary image file is stored in a secondary image database. The secondary image file may be compressed using a compression format suitable for images, such as JPEG.

Upon receipt of the secondary image file at step (202), the secondary image file is sent for processing (204). The received secondary image file may depict a plurality of subjects, with each subject having respective one or more characteristics that are unique to the subject. In one embodiment, processing may include identification of at least one subject of the secondary image file to facilitate a targeted associated with at least one primary image. In one embodiment, some or all of the image data processing may occur on site using quickly deployable technology, such as field-programmable gate arrays (FPGAs).

The processing starts with identifying the number of subjects in the secondary image (206). It is understood that each image will have a minimum of one subject. In one embodiment, if the secondary image does not include the minimum number of subjects, the secondary image may be discarded. The variable XTOTAL is assigned to the number of subjects in the secondary image (208). For example, for a secondary image having three subjects, XTOTAL is set equal to three. A subject counting variable X is initialized (210). One or more characteristics of subjectX are extracted and processed from the secondary image (212). In one embodiment, the one or more characteristics of subjectX correspond to facial features of subjectX, including but not limited to hair color, eye color, skin color, etc. Depending on the algorithm used, the features may be automatically extracted, and in one embodiment they may be non-intuitive to us humans—as in deep convolutional neural networks or DBNs, etc. For instance, feature extractors today tend to do so hierarchically by first extracting edges, then, building upon these edges, they form higher-level features, which may not be as recognizable as hair color, eye color, etc.

The purpose of processing the characteristics of subjectX is to find at least one primary image in the primary image database that corresponds to one of the subjects identified in the secondary image. A counting variable Y for each primary image is initialized (214). One or more characteristics from primary imageY of the primary image database are extracted and processed (216). In one embodiment, the variable Y is indexed to correspond to the particular unique identifier, IDP, of the primary image. That is, imageY corresponds to the primary image file having IDP=Y. It is understood that a comparison of characteristics should be based on a correspondence. In one embodiment, the subject of the extracted characteristics of the primary image directly corresponds to the subject of the secondary images. Specifically, if hair, eye, and skin color are extracted from the secondary image(s), hair, eye, and skin color are extracted from each primary image. Once the characteristics of the primary and secondary images are completed and available, the one or more characteristics of subjectX are compared to the one or more characteristics of imageY to produce a relevance score of subjectX, scoreX,Y (218).

The relevance score is a metric used to quantify a relevance relationship between the subject of the secondary image and the primary image. In one embodiment, the relevance score may be less than a complete correspondence. For example, if four characteristics are compared three of which match, the score would be 75%. In one embodiment, the score may be employed at a later point in time as a confidence measurement, and to increase the likelihood of a match to the primary image. A variety of techniques and calculations for producing the relevance score are known in the art, and a person having skill in the art would know how to implement such techniques. With respect to relevance scoring, decaying probability may be applied to each individual to increase the likelihood of getting good matches. For instance, if a user walks in to the park, the strength of their probability could be some factor Tentry, and based upon statistics for how long people tend to be in the park, after say Tentry+tavg_expected the factor that would multiply by all of their relevance calculations may start decreasing, thereby decreasing the likelihood that pictures after that point will be associated with them. This could also be used to prune out users from the relevance scoring process to speed up the calculation. In one embodiment, Tentry could be equal to 1, and start decreasing after Tentry+tavg_expected by some factor. This is also very practical in that in most social environments, individuals tend to move around more in the beginning of the event than at the end of it. For example, individuals in a waterpark are more active closer to the time that they arrive at the park, than at the end—at which point they are more likely to be sitting down eating, or sitting down in the lazy river.

In one embodiment, the relevance score is compared to a threshold (220). It is understood that the threshold represents a numerical likelihood of a match between the compared characteristics. In one embodiment, the threshold may be subject to change. Following step (220), it is determined if the relevance score exceeds the threshold (222). A negative response to the determination at step (220) indicates that the characteristics of subjectX are an insufficient match to the characteristics of imageY, and it is likely that the primary and secondary images under evaluation do not match. The counting variable Y is increased (224), and the process reverts back to step (216). An affirmative response to the determination at step (222) indicates that the characteristics of subjectX are a sufficient match to the characteristics of imageY, and the secondary image file is assigned to the primary image group of imageY (226). In one embodiment, the assignment of the secondary image file to the primary image group includes linking the secondary image file to the primary image file. The counting variable X is increased (228), and it is determined if there are additional subjects in the secondary image that have not been evaluated with respect to a primary image (230). A negative response to step (230) is followed by a return to step (212), and an affirmative negative response to step (230) means that each subject in the secondary image has been evaluated (232), and in one embodiment assigned to a respective primary group.

Steps (202)-(230) as described above may be performed by image recognition algorithms and/or software, such as facial recognition algorithms and/or software. Examples of such software are known in the art, and details with respect to the implementation of image processing and/or image recognition software will not be provided herein.

In one embodiment, a representation of a primary image group may be displayed or viewed (234). For example, the primary image group may be displayed on a visual display device located near the exit of the venue. This allows a patron to view the collection of images assigned to the patron's primary image group, prior to choosing whether or not to purchase one or more of the images. In one embodiment, the patron has the option of purchasing individual images of the primary image group, a subgroup of the primary image group, or the entire primary image group. The images that are purchased may be printed out on site, or may be sent to the patron via e-mail, regular mail, etc. Accordingly, the method described above in the context of FIGS. 1 and 2 allows for the autonomous capture and association of images and video, thereby enabling a patron to purchase one or more photographs or videos at a single location.

The method of FIGS. 1 and 2 is focused on grouping pictures based upon analyzing the characteristics of image subjects. It is understood that an individual may be a part of a larger group of people. Different algorithms may be invoked to assign images to a primary image folder. Referring to FIG. 3, a flow chart (300) is provided illustrating a process for dynamically adding images and video to the folder. As shown and described in FIGS. 1 and 2, an association between the primary image and at least one secondary image is created (302). From this association, the primary image identifier is extracted (304), and a secondary image identifier is extracted for a secondary subject determined or considered to be associated with the primary image (306). With these extracted identifiers, the image and video databases are searched for any images and/or video that contains both of these identifiers (308). Any images and/or video that match are assigned to the primary image folder (310). In one embodiment, the matching images and/or video area also assigned to an image folder for the secondary image (312). Accordingly, the process shown herein populates the folders of the identifiers ascertained to have a relationship.

The process of populating the individual folders should not be limited to that shown and described herein. Other grouping algorithms may be employed. For example, in one embodiment, a clustering algorithm may be used to track faces of patrons in images, and then any images with the same combination of associated identifiers may be placed in the image folder of each of the identified patrons. Similarly, a threshold of likelihood of a match may be lowered to increase the number of images placed in the folder, or raised to lower the number of images placed in the folder. In one embodiment, the threshold level is present, and an associated threshold value may be modified. In addition, the population of the folder may be updated dynamically, or at discrete time intervals.

Referring to FIG. 4, a flow chart (400) is provided illustrating a process for reviewing the generated associations. The reviewing process is shown to occur as a patron is exiting the venue. In one embodiment, the viewing may occur while the patron is at the venue, or in another embodiment the patron may remotely participate in the review process through connection to a shared resource, i.e. cloud computing. As shown, the patron enters an identifier into a portal (402). The identifier may be a ticket the patron received upon entrance to the venue. The primary image associated with the identifier is presented to the patron for verification (404), and an image or a group of images assigned to the folder associated with the identifier are presented to the patron (406). In one embodiment, the images are presented on a visual display. The patron may contribute to the association process. As shown herein, the patron may select any image in the folder that is not relevant, e.g. does not belong, for removal from the patron's folder (408). In one embodiment, the patron may invoke inverse logic for the selection process. Similarly, in one embodiment, all of the pictures may be considered relevant. An image selected at step (408) for removal may feature multiple patrons, and it may be important to note the specific patron depicted being correlated to the patron who is removing the image. In such a scenario, the removal at step (408) may include identifying which patron in the image is being rejected. In one embodiment, this identification prevents the image from being assigned to the patron's folder again in the future.

Step (408) may further include an autonomous reassignment of the removed image to a folder of another patron. In one embodiment, an image is reassigned to the folder of a patron having the next highest relevance score exceeding the threshold. For the sake of illustration, say an image was correlated with four patrons, PatronA, PatronB, PatronC, and PatronD. It was previously determined that for a threshold relevance value set at 65%, PatronA has a relevance score of 80%, PatronB has a relevance score of 78%, PatronC has a relevance score of 70%, and PatronD has a relevance score of 50%. Since it was initially determined that PatronA has the highest relevance score, the image was initially assigned to the folder of PatronA. If PatronA flags or otherwise identifies the image as irrelevant, the image will be automatically reassigned to the folder of PatronB. Similarly, if PatronB then flags or otherwise identifies the image for removal, the image will be automatically reassigned to the folder of PatronC. However, if PatronC flags the image for removal, the image will not be automatically reassigned to PatronD because the relevance score of 50% is less than the 65% threshold relevance value. In one embodiment, the image may be deleted or otherwise permanently discarded if there are no patrons having a sufficiently high relevance score remaining.

Accordingly, the first part of the process shown herein is for the filter to review and parse through the images and video assigned to their folder.

Following the selection process at step (408), the quantity of images removed from the folder is assigned to the variable XTotal (410), and an associated counting variable, X, is initialized (412). The identifier for both the primary subject and the identified secondary subject in the imageX are extracted (414). In one embodiment, the images being removed have been determined to have a relationship upon patrons that does not exist. The association of the images is removed. In one embodiment, the image database is searched for all images that contain the identifiers of both the primary subject and the secondary subject to remove the created association in both the image folders of the primary and secondary images (416). Following step (416), the image counting variable is incremented (418) and it is determined if all of the images subject to discard have been removed (420). If any images for review remain, the process returns to step (414). Once the review of all of the removed images is completed, the process continues with the primary patron reviewing the remaining images and video and selecting any one of the images or video for purchase or download (422). In one embodiment, a watermark may be used in pictures to prevent users from taking screenshots of pictures to avoid paying. It is understood that the actions of one patron may affect the image presentation of other patrons. In one embodiment, the removal of images from a patron's folder may be limited to their folder and may not affect the population of another patron's folder. This would provide a limited removal so that the actions of one patron are limited to that patron, and would enable the secondary subject to determine relevance or interest in the image of video when reviewing their image group folder in their portal.

With reference to FIG. 5, a block diagram (500) is provided illustrating an example of a computer system/server (502) with tools to support image classification for implementing the process described in the context of FIGS. 1-4. The image classification system is operational with numerous other general purpose or special purpose computing system environments or configurations. Examples of well-known computing systems, environments, and/or configurations that may be suitable for use with the image classification system include, but are not limited to, personal computer systems, server computer systems, thin clients, thick clients, hand-held or laptop devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputer systems, mainframe computer systems, and distributed cloud computing environments that include any of the above systems or devices, and the like.

The image classification system may be described in the general context of computer system-executable instructions, such as program modules, being executed by a computer system. Generally, program modules may include routines, programs, objects, components, logic, data structures, and so on that perform particular tasks or implement particular abstract data types. The image classification system may be practiced in distributed cloud computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed cloud computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices.

As shown in FIG. 5, the image classification system is implemented in the form of a general-purpose computing device. The components of the image classification system may include, but are not limited to, a server (510) configured with one or more processors or processing units (512), system memory (516), and a bus (514) that couples various system components including system memory (516) to processor (514). Bus (514) represents one or more of any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, and a processor or local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnects (PCI) bus. The image classification system typically includes a variety of computer system readable media. Such media may be any available media that is accessible by the image classification system and it includes both volatile and non-volatile media, removable and non-removable media.

Memory (516) can include computer system readable media in the form of volatile memory, such as random access memory (RAM) and/or cache memory. The image classification system further includes other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system (540) can be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to bus (514) by one or more data media interfaces. As will be further depicted and described below, memory (516) may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of the embodiments described herein.

Program/utility (526), having a set (at least one) of program modules (528), may be stored in memory (516) by way of example, and not limitation, as well as an operating system, one or more application programs, other program modules, and program data. Each of the operating systems, one or more application programs, other program modules, and program data or some combination thereof, may include an implementation of a networking environment. Program modules (528) generally carry out the functions and/or methodologies of embodiments as described herein. For example, the set of program modules (528) may include at least one module that is configured to compare the primary image (544) with one or more characteristics of the secondary image (548) to produce a relevance score of the secondary image, and to convert the relevance score to an assignment of the secondary image by selectively assigning the secondary image to a primary image group (542) based on the relevance score. The primary image group (542) is shown herein stored on persistent storage device (540), although in one embodiment, the image group (542) may be stored in one or more components of memory (516).

The image classification system (530) is shown herein embedded in memory (516). The image classification system (530) is configured to communicate with one or more external devices, including but not limited to a primary camera (502), a secondary camera (504), and visual display (506). The primary camera (502) is configured to capture the primary image (544), and the secondary camera (504) is configured to capture respective secondary image(s) (548). The primary camera device (502) and the secondary camera (504) are in communication with memory (516) and, upon capture, the primary and secondary images (544) and (548) are stored in one or more components of memory (516) for processing, and in one embodiment stored in persistent storage (540). Visual display (506) may be configured to display a representation of an image group, such as primary image group (542) that includes the primary image (544) and each secondary image (548) that is determined to be sufficiently relevant to the primary image. For example, any secondary image linked to the primary image (544) may be communicated to the visual display (506) associated with a request to view images in the first group (542).

The image classification system (536) may also communicate with one or more devices (560) that enable a user to interact with the image classification system and/or any devices (e.g., network card, modem, etc.) that enable the image classification system to communicate with one or more other computing devices. Such communication can occur via Input/Output (I/O) interface(s). Still yet, the image classification system (536) can communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via network adapter (530). As depicted, network adapter (530) communicates with the other components of the image classification system (536) via bus (514). In one embodiment, the primary and secondary images (544) and (548) may be received by the server (510) from the primary and secondary cameras (502) and (504), respectively, and communicated by the network adapter (530) to memory (516) via bus (514) for storage. It should be understood that although not shown, other hardware and/or software components could be used in conjunction with the image classification system (402). Examples, include, but are not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc.

As shown herein, the images may be presented on a visual display (506), which is shown in communication with the server (510). In one embodiment, the image classification system is accessed via a portal as supported by a client machine (560). The client machine (560) is shown herein with a processing unit (562) in communication with memory (566) across bus (564). The client machine (560) is shown with a transaction module (570) in communication with memory (566). In one embodiment, the transaction module (570) is located on the server (510) and is accessed by the client machine (570) via the network adapter (530). The transaction module (570) converts the image assignments, classification into groups, and associated relevance scores, into an interface to support a commercial transaction for purchase of selective image files.

The process shown in FIGS. 1-4 and the computer system shown in FIG. 5, may be incorporated into a cloud based system that supports local and remote image management in a shared resource environment. As is known in the art, cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models. Example of such characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based email). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

Referring now to FIG. 6, a schematic of an example of a cloud computing node (600) is shown. Cloud computing node (610) is only one example of a suitable cloud computing node and is not intended to suggest any limitation as to the scope of use or functionality of the embodiments described herein. Regardless, the cloud computing node is capable of being implemented and/or performing any of the functionality set forth hereinabove.

In cloud computing node (610) there is a computer system/server (612), which is operational with numerous other general purpose or special purpose computing system environments or configurations. Examples of well-known computing systems, environments, and/or configurations that may be suitable for use with computer system/server (612) include, but are not limited to, personal computer systems, server computer systems, thin clients, thick clients, handheld or laptop devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputer systems, mainframe computer systems, and distributed cloud computing environments that include any of the above systems or devices, and the like.

Computer system/server (612) may be described in the general context of computer system executable instructions, such as program modules, being executed by a computer system. Generally, program modules may include routines, programs, objects, components, logic, data structures, and so on that perform particular tasks or implement particular abstract data types. Computer system/server (612) may be practiced in distributed cloud computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed cloud computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices.

As shown in FIG. 6, computer system/server (612) in cloud computing node (610) is shown in the form of a general-purpose computing device. The components of computer system/server (612) may include, but are not limited to, one or more processors or processing units (616), a system memory (628), and a bus (618) that couples various system components, including system memory (628) to processor (616).

Bus (618) represents one or more of any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, and a processor or local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnect (PCI) bus.

Computer system/server (612) typically includes a variety of computer system readable media. Such media may be any available media that is accessible by computer system/server (612), and it includes both volatile and non-volatile media, removable and non-removable media.

System memory (628) can include computer system readable media in the form of volatile memory, such as random access memory (RAM) (630) and/or cache memory (632). Computer system/server (612) may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system (634) can be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g. a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to bus (618) by one or more data media interfaces. As will be further depicted and described below, memory (628) may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of embodiments.

Program/utility (640), having a set (at least one) of program modules (642), may be stored in memory (628) by way of example, and not limitation, as well as an operating system, one or more application programs, other program modules, and program data. Each of the operating system, one or more application programs, other program modules, and program data or some combination thereof, may include an implementation of a networking environment. Program modules (642) generally carry out the functions and/or methodologies of the embodiments as described herein.

Examples of these local computing devices include, but are not limited to, personal digital assistant (PDA) or cellular telephone (720), desktop computer (730), laptop computer (740), and/or automobile computer system (750). Individual nodes within nodes (710) may further communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment (700) to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices (720)-(750) shown in FIG. 7 are intended to be illustrative only and that computing nodes (710) and cloud computing environment (700) can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

Referring now to FIG. 8, a set of functional abstraction layers provided by cloud computing environment (800) is shown. It should be understood in advance that the components, layers, and functions shown in FIG. 8 are intended to be illustrative only, and the embodiments are not limited thereto.

In the shared pool of configurable computer resources described herein, hereinafter referred to as a cloud computing environment, files may be shared among users within multiple data centers, also referred to herein as data sites. A series of mechanisms are provided within the shared pool to provide decision making controls for access to one or more records based upon associated record access and inherent characteristics of privacy. Three knowledge bases are employed with respect to consent management, including importance, sensitivity, and relevance. Analytical techniques employ the knowledge bases to assist with making access control decisions. With respect to the image classification, management, and selection, image files may be stored on a data storage device of a shared resource, and the tools to support the classification, management, and selection of images files may similarly be stored on a shared resource. As such, the cloud based support enables a patron to access the image management system through the cloud. In one embodiment, the patron may access the image management system with image presentation and selection limited to image files in a folder assigned to a specific identifier. The patron mayo execute a transaction for obtaining the image files via the cloud, with transfer of an electronic file to a portal in communication with the cloud once the transaction has been completed. Accordingly, the shared resource implementation enables and supports transaction with the image management system.

The corresponding structures, materials, acts, and equivalents of all means or step plus function elements in the claims below are intended to include any structure, material, or act for performing the function in combination with other claimed elements as specifically claimed. The description of the embodiments herein has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the embodiments in the forms disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the embodiments described herein. The embodiments were chosen and described in order to best explain the principles and the practical application, and to enable others of ordinary skill in the art to understand the various embodiments with various modifications as are suited to the particular use contemplated. Accordingly, the implementation of image classification shown and described herein creates a primary image group that includes a generated primary image and a received secondary image assigned to the primary image group based on a relevance score of the secondary image.

It will be appreciated that, although specific embodiments have been described herein for purposes of illustration, various modifications may be made without departing from the spirit and scope of the specific embodiments described herein. Details of the embodiments have been described with respect to an entertainment venue, such as an amusement park. However, the processes and systems described herein may be employed in a variety of venues where images may be acquired.

For example, the processes and systems described herein may be employed in the context of providing security at a venue, such as a secured site. Such secured sites may include, but are not limited to, schools, university campuses, prisons, etc.

Each person authorized to be at the site may be required to go through an initial registration process. This initial registration process may include capturing a primary image of a registrant to the site. The primary image is then assigned to a profile corresponding to the registrant. In one embodiment, the registrant is given a device, such as a keycard or other form of identification, for use in an identity verification system. The device provides a link to the registrant's profile in the image database. If a person wishes to gain access to the site, the person has to utilize the device (e.g., swipe a keycard). In another embodiment, a secondary camera may be used to capture a secondary image of a person attempting to enter the site. The system may then compare the captured secondary image to the primary image database to determine if the person is authorized, and to grant or deny access to the person in response to the comparison.

A network of secondary cameras may be set up within the site itself to capture one or more secondary images of each person periodically while in the site. In one embodiment, the system may be configured to automatically generate a path corresponding to a person by correlating the periodically captured secondary images, and piecing them together to assemble a pattern. If the location of the person is considered to be erratic, or the pattern the person is traversing appears to be suspicious or otherwise irregular, the system may be configured to alert a system administrator. In one embodiment, the alert includes one or more of the secondary images of the suspect person. Furthermore, the system may compare the one or more secondary images of the suspect person with the primary image database to determine if the suspect person is authorized to be at the site. If it is determined that the suspect person has not registered into the system (i.e., is an intruder) based on the comparison, an intruder alert may be issued to the system administrator. In one embodiment, the system can assemble the path that the intruder has taken to determine where the intruder has travelled within the site. This may provide information regarding locations that were breached by the intruder.

As another example, the processes and systems described herein may be employed in the context of an automated storage system, such as with a storage unit. The owner(s) of the storage unit may be required to go through an initial registration process with the storage unit. The initial registration process may include capturing a primary image of each owner. The primary image is then assigned to profile(s) corresponding to the owner(s). In one embodiment, each owner is given a device, such as a keycard or other form of identification, for use in an identity verification system to access the storage unit. The device provides a link to the registrant's profile in the image database. If a person wishes to gain access to the site, the person has to utilize the device (e.g., swipe a keycard). In another embodiment, a secondary camera may be used to capture a secondary image of a person attempting to access the storage unit. The system may then compare the captured secondary image to the primary image database to determine if the person is an owner of the storage unit, and to grant or deny access to the person in response to the comparison.

Furthermore, storage unit contents may be monitored within the storage unit itself. In one embodiment, a primary image of each object is captured. One or more secondary cameras may be placed within the storage unit to periodically analyze the contents within the storage unit. This may allow the owner to determine the location of an object inside the storage unit, which can be especially useful in the context of large storage units (e.g., warehouses) that house many items. In one embodiment, the one or more secondary cameras may be configured to detect when an object is removed from the storage unit. In one embodiment, the automated storage system may automatically remove the image of the object from the image database in response to the removal. In another embodiment, the automated storage system may notify the owner that the object has been removed.

In yet another example, the processes and systems described herein may be employed in the context of a home automation system, which may include a home security system. Each family member may be required to go through an initial registration process. This initial registration process may include capturing a primary image of each respective family member. Additional people may also be registered, such as extended family, friends, etc. The primary image is then assigned to a profile corresponding to a respective person.

A network of secondary cameras may be set up within and around the home to periodically capture one or more secondary images. In one embodiment, the system may be configured to determine the presence of a potential intruder entering the house by comparing one or more captured secondary images to the primary image database. If the comparison determines that a captured secondary image does not match a primary image in the database, then an alert may be automatically issued (e.g., an alarm). In another embodiment, the system may be further configured for child safety purposes. For example, if a comparison of a captured secondary image to the primary image database indicates that a baby or other small child has left a designated area or entered a restricted area, either of which may be specified via a system interface, an alert may be issued to the family (e.g., via a mobile application, web interface, etc.). alert includes one or more of the secondary images of the suspect person. The home automation system may be configured for a variety of other purposes, such as in the context of smart home technology.

As discussed above, the processes and systems described herein may be employed in a variety of unique contexts and venues. These contexts include, but are not limited to, image capturing and storage, security systems (e.g., for secured sites), object identification and tracking systems, and localized automation systems.
